Estimate the azimuth resolution of a side-looking airborne SAR operating in broadside at a wavelength of 0.03 m for a target range of 10 km. The radar has a synthetic aperture length of 195 m and a range impulse broadening factor of 1.3.
lambda = 0.03;
len = 195;
R = 10e3;
azb = 1.3;
Compute the azimuth resolution for the synthetic aperture.
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN, where Name is
the argument name and Value is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Before R2021a, use commas to separate each name and value, and encloseNamein quotes.
Azimuth impulse broadening factor due to data weighting or windowing for sidelobe control, specified as a positive real scalar. This argument expresses the actual –3 dB mainlobe width with respect to the nominal width. Typical window functions like hamming and hann exhibit values in the range from 1 to 1.5.
Data Types: double
Coherent integration angle in degrees, specified as a scalar in the range
[0, 180]. This argument specifies the angle
through which the target is viewed during the coherent processing aperture.
Data Types: double
Doppler cone angle in degrees, specified as a scalar in the range [0,
180]. This argument identifies the direction toward the scene
relative to the direction of motion of the array.
Azimuth or cross-range resolution in meters, returned as a matrix. The rows of
azres correspond to the range values in r
and its columns correspond to the wavelength values in
lambda.
